IMPROVEMENT IN OlL CAN NOZZLES.

Specification forming part of Letters Patent No. 219.103. datedSeptember 2, 187!) application filed May 10, 1879. i

To all whom it may concern:

Be it known that I, IRA LEONARD, of Lowell, in the county of Middlesexand Commonwealth of Massachusetts, have invented new and usefulImprovements in Oil-Gan Nozzles, of which the following is aspecification.

My invention consists in inserting a tapering pin provided withlongitudinal lateral grooves in the outer end of the nozzle of a canintended for applying oil to machinery, and also in flaring the outerend of said nozzle, for the purposes herein described.

In the accompanying drawings, Figure 1 represents a'can to which my invention is attached, the can and nozzle being in vertical cross-sectionand Fig. 2 represents an enlarged horizontal cross-section of the nozzleand pin, taken on the dotted line in Fig. 1.

A is a can constructed in theusual manner. To the can is screwed, or byother well-known means attached, the vertical nozzle B, which should bethick enough to avoid denting, and is better if made of cast metal, sothat the outer end cannot so well be enlarged by operatives. The upperend of said nozzle is flared to form a cup at E, which receives thesurplus oil that runs down the pin 0 after oiling.

The pin 0 is tapered at the top to a point, so that the oil may bereadily delivered from its upper end, and has one or more grooves, D,running from its lower end to a point above the top of the nozzle, thegrooves disappearing on the tapering part of the pin. The pin 0 isprovided with a screw-thread on its lower end, which is, therefore, inappearance like a tap used to cut female screws, and which lower endenters a screw-thread cut on the inside of the top of the nozzle B. Thepin should be screwed into the nozzle so firmly that it cannot beremoved without tools. Below the pin 0 the nozzle B has an enlargedinternal diameter, F, so that the oil may readily reach the top of thenozzle.

The can and nozzle above described are used like other cans, the oilrunning in the grooves 1) between the pin and the top of nozzle andfollowing the pin to its point.

The advantages of my invention are that operatives cannot readilyenlarge the deliveryorifice,-(by thursting into it a wire, nail, or thetang of a file, for instance,) and thereby waste the oil, that thenozzle is kept clean on its outer surface, and that the pin withtapering point gives a perfect direction to the oil.

I claim as my invention 1. The combination of the nozzle B and the pin(3, tapered and provided with the groove D, as and for the purposedescribed.

2. The combination of the nozzle B, pro vided with the cup E, and thepin 0, tapered and provided with the groove D, as and for the purposedescribed.
